1. The domain is (-2, -1, 0, 1) the rage is (4,2,0,2) 2. It is a function
Step-by-step explanation:
The domain in a pair is always the first number. The range is always the second number in the ordered pair.
Answer:
Domain: {−2,−1,0,1}
Range: {0,2,4}
Step-by-step explanation:
The domain is all the x-coordinates, but NEEDS TO BE ORDERED, which are {−2,−1,0,1} and you also need to include the curly brackets { }.
The range is all the y-coordinates and also NEEDS TO BE ORDERED, which are {0,2,4} and you also still need to include those curly brackets { }.
Hope this helps and answers your question! :)

A population of bees is decreasing. The population in a particular region this year is 1250. After year 1, it is estimated that the population will be 1000. After 2 years it is estimated that the population will be 800. How many years will it take for the bee to be below 100?
Answers
Answer:
1250 => 250 ( subtracted from the balance population )
1000 => 300
800 => 350
450. => 400
50.
So it will take around 5 years I think to be below 100.

Tuesday, I bought 5 shirts and 8 pairs of pants for a total cost of $18.75. Can you
find the price of each item?
Answers
Step-by-step explanation:
Step one:
given data
let the shirts be x
and the pants be y
Required
the number of shirts and pants
the systems of the equation for the situation is
2x+6y=11-------------1
5x+8y=18.75-------2
2x+6y=11-------------1X 5
5x+8y=18.75-------2 X2
10x+30y=55-------------1
-10x+16y=37.5-------2
0x+14y=-17.5
divide both sides by 14
y=17.5/14
y=1.25
pants= $1.25
put y=2.32 in eqn 1 2x+6y=11
2x+6(1.25)=11
2x+7.5=11
2x=11-7.5
2x=3.5
x=3.5/2
x=$1.75

The basketball team spends 20 minutes running laps and at least 15 minutes discussing plays. Practice lasts one hour and 45 minutes. Write an inequality to represent the amount of time to work on other drills. Just type in the final answer. Let: x=other drills
Answers
Answer:
x ≤ 75
Step-by-step explanation:
The computation of the inequality function is as follows:
Let us assume the remaining time left for other drills be x
Given that the team spends 20 minutes for running laps
And minimum of 15 minutes for discussing plays
Also practicing for last one hour and 45 minutes
Now as we know that
1 hour = 60 minutes
So total minutes would be
= 60 + 45
= 105 minutes
Total minutes spend by the team is
= 20 + 15
= 35 minutes
So now the remaining time left is
x ≤ 105 - 35
x ≤ 75

x = independent variable
y = dependent variable
Number of swimmers when temperature = 88
y = 1.5045(88) - 88.2056

A washer and a dryer cost $834 combined. The washer costs $84 more than the dryer. What is the cost of the dryer?
Answers
W = D + 84
Use substitution
D + 84 + D = 834
2D = 750, D = 375
The cost of the dryer is $375
Answer:
The dryer cost $375
Step-by-step explanation:
834/2 = 417
84/2 = 42
417 - 42 = 375
834 - 375 = 459
459 - 84 = 375
PROOF: 417 - 375 = 42 then double that answer to get 84

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 45 minutes? In 1 hour?
Answers
Answer:
33.75 miles in 45 minutes,
45 miles in an hour
Step-by-step explanation:
45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,
1 3/4= 7/4 ---> 7/4*3=5.25
car travels 5.25 miles for every 7 minutes,
45/7*5.25= 33.75 miles
1 hour (60 minutes):
using that the car travels 5.25 miles for every 7 minutes,
60/7*5.25= 45 miles

What value of R makes r/ -11 = (-3) true
Answers
Answer:
The value of [tex]r=33[/tex] which makes the equation true.
Step-by-step explanation:
Given the equation
[tex]\frac{r}{-11}=-3[/tex]
We have to find the value of r for which the equation must be true.
solving the equation
[tex]\frac{r}{-11}=-3[/tex]
Multiply both sides by -11
[tex]\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)[/tex]
[tex]r=33[/tex]
Therefore, the value of [tex]r=33[/tex] which makes the equation true.
VERIFICATION:
Putting [tex]r=33[/tex] in the equation
[tex]\frac{r}{-11}=-3[/tex]
[tex]\frac{33}{-11}=-3[/tex]
[tex]-3=-3[/tex] ∵ [tex]\frac{33}{-11}=-3[/tex]
L.H.S = R.H.S
Therefore, the value of [tex]r=33[/tex] which makes the equation true.

Answers
Answer:
x column- 1.25, 7.5, 45.
y column- 5, 30, 180.
Step-by-step explanation:
Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.

Answers
Answer:
The correct option is;
D. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent
Step-by-step explanation:
In the proof to show that the sum of the angles in a triangle = 180°, we have;
For a triangle located between two parallel lines, such that the base of the triangle coincides with one of the parallel lines, we have;
The angle formed by one of the base angles and the adjacent side of the extension = 180° by the sum of angles on a straight line
From the attached diagram of a triangle between two parallel lines, we have;
∠e + ∠b = 180° by the sum of angles on a straight line postulate
∠e = ∠a + ∠d by alternate interior angles postulate
∠c = ∠d by alternate interior angles postulate
∴ ∠e = ∠a + ∠c by substitution property
∴ ∠e + ∠b = ∠a + ∠c + ∠b = 180° by substitution property
Therefore, the sum of the interior angles of a triangle, ∠a + ∠c + ∠b = 180°.
